“Every new medium transforms the nature of human thought. In the long run, history is the story of information becoming aware of itself.”

“When information is cheap, attention becomes expensive.”

“For the purposes of science, information had to mean something special. Three centuries earlier, the new discipline of physics could not proceed until Isaac Newton appropriated words that were ancient and vague—force, mass, motion, and even time—and gave them new meanings. Newton made these terms into quantities, suitable for use in mathematical formulas. Until then, motion (for example) had been just as soft and inclusive a term as information. For Aristotelians, motion covered a far-flung family of phenomena: a peach ripening, a stone falling, a child growing, a body decaying. That was too rich. Most varieties of motion had to be tossed out before Newton’s laws could apply and the Scientific Revolution could succeed. In the nineteenth century, energy began to undergo a similar transformation: natural philosophers adapted a word meaning vigor or intensity. They mathematicized it, giving energy its fundamental place in the physicists’ view of nature.It was the same with information. A rite of purification became necessary.And then, when it was made simple, distilled, counted in bits, information was found to be everywhere.”

“Evolution itself embodies an ongoing exchange of information between organism and environment .... The gene has its cultural analog, too: the meme. In cultural evolution, a meme is a replicator and propagator — an idea, a fashion, a chain letter, or a conspiracy theory. On a bad day, a meme is a virus.”

“Information is not knowledge and knowledge is not wisdom.”

“We have met the Devil of Information Overload and his impish underlings, the computer virus, the busy signal, the dead link, and the PowerPoint presentation.”

“With words we begin to leave traces behind us like breadcrumbs: memories in symbols for others to follow. Ants deploy their pheromones, trails of chemical information; Theseus unwound Ariadne's thread. Now people leave paper trails.”
